1. Manual Wafer Butterfly Valve Description：
A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required.

5.FAQ
1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.
3. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
- Q: Chev 350 in marine use. Made horiffic exhaust noise, especially with increasing throttle. Cam seems fine still, but the rocker on #5 exhaust was somewhat off to the side but still touching the side of the valve stem...but stem bent. What would cause this and is this the cause of the loud combustion sound (like a spark plug out of it's hole?
- make sure you dont have any of the spark plug wires crossed (like 5 7). If you do, you'll get a backfire out of the exhaust or carb.
- Q: I have a 87 cbr600, consumes oil at a considerable rate. Took the engine out of the frame and disassembled cylinder head, block and pistons and found there is a thick layer of cooked-on oil over all sixteen valves. I figured the oil consumption was due to bad rings, but could it have been the valves?
- Yep! I'd do the rings too! Pish posh on bravery, if you have the manual, anything you break is replaceable!
- Q: A reading from my 2002 ford explorer said insufficient flow from the EGR valve. Would it be possible to clean the valve or fix it or would I need to buy a whole new valve?
- I have replaced several DPFE's for this reason. Never had to replace an EGR valve for the insufficient flow code. Like previously posted best to get a genuine Ford DPFE
- Q: The pump is working fine on the presta valve on my back tire, but it is not working on the other presta valve. It seems like the the presta valve isn't sticking out far enough out of the tube for the pump to be able to lock in on it. What could be causing this?
- to apply the adapter, you need to first unscrew the presta valve, then placed the adapter on and pump up the tire, then take the adapter off and tighten the presta valve to close it. I consider the different answer that that's recommended to replace the tubes so as that the presta valve does not come aside. New tubes are inexpensive - approximately $6 or so. you need to purchase a spare, too, merely in case you flat. in case you do no longer understand the thank you to alter the tubes, your community motorbike save can do this for you and clarify the technique so as which you're able to do it your self interior the destiny and sell you the tire levers (and patch kit in case you want) you will ought to do it. reliable success!
- Q: compare the structure of the tricuspid valve with that of the pulmonary valve??please help me
- Inga, Valves are flap-like structures that allow blood to flow in one direction. The tricuspid valve is located between the right atrium and the right ventricle and prevents the back flow of blood as it is pumped from the right atrium to the right ventricle. The pulmonary valve is the structure in the pulmonary artery consisting of three flaps, which open and close during each heartbeat. The flaps keep blood from flowing back into the heart from the pulmonary artery which is the artery that supplies blood to the lungs. Hope this helps matador 89

- Q: My 4.0 L V6 2002 Ford Explorer has this plastic casing on top of the intake manifold...some of the hoses (brake booster, etc) are actually connected to the plastic casing, now how can i replace my pcv valve?
- The PCV Valve is not connected to your brake booster. If it were, engine oil and other debris would be pulled into the booster diaphragm and contaminate it and destroy it. Your PCV Valve is located on one of your Valve Covers. The Valve Covers are the long metal lids that run the full length of your engine on either side. Normally your oil cap is also located on one of the covers so you can fill your engine with oil when needed. The part that you are looking for is normally made of plastic or metal, and it is seated in a rubber grommet in one of the valve covers. You will normally find a single rubber hose coming from it leading to either your air cleaner or a port on the intake plumbing. Normally located before the throttle body. The PCV Valve itself, is a cylindrical object that is normally about 1/2 inch to 3/4 inch round and about an inch to 1.5 inches tall with a single, (sometimes double) port at the top. There is an object on your intake manifold, and sometimes also located below your throttle body, that does look like a PVC Valve. But its not. Its a simple vacuum port connector for access to manifold vacuum to operate things like your brake booster, and some of the emission control devices. I hope that helps you out. Good Luck!
- Q: Hi there - We have an old house with galvanized steel pipes. Our main water shut off valve leaks -- the leak is from the packing nut. A plumber came out yesterday and tightened it, and it now barely leaks at all, maybe one drip every 24-48 hours (which it probably has been doing for the 6 years we have lived here, we just didn't know when we bought the place). Rather than replacing the whole valve (which, apparently, has a high liklihood of breaking the pipes in the foundation, requiring jackhammering and whatnot), we are thinking of installing a new shut off valve higher up on the pipe, where I guess it's less likely to break. If we go for the second valve, is there a way to close up that old valve (hydraulic cement, tape, solder, etc.), so it doesn't leak at all? The tiny leak is coming from the stem of the handle - can we remove the handle and cap it off or something? (And thanks to those of you who answered my husband's question about the pipes yesterday!)

- Q: Electric Hot Water Tank Pressure Release Valve Leaking, Why?
- did you recently increase the heat settings or change a thermostat? an increase in temperature can cause the pressure relief to go off a little...but usually only when the temperature gets up there (160-180oF) which is uncommon for electric. Unless the valves are shut off above the tank, the piping system should handle any pressure increase in an electric tank. Do you have a buffer tank on the hot water side? (usually only when you have hydronic heat) it could be saturated or pre-charged too high. If none of the above are probable, you may just have a bad pressure relief valve, I've changed one before, had to turn off the cold water and open up a cold tap to let all the pressure out of the system, bleed off the hot water until the pressure valve didn't spit out when I opened it, unscrewed the plastic downpipe from the valve(some have it, some don't) and remove/replace it with some teflon tape on the new one (20 bucks or so from the home depot)
- Q: Mitral valve prolapse have impression on lifetime?please answer with source
- Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL.
